We show that a time-dependent scattering theory can be constructed, and the scattering matrix is a pseudodifferential operator on each energy surface. Moreover, the principal symbol of the scattering matrix is given by a Born approximation type function. The main motivation of the study comes from applications to discrete Schr\\\"odigner operators, but it also applies to various differential operators with constant coefficients and short-range perturbations on Euclidean spaces.", "revisions": [ { "version": "v1", "updated": "2014-07-31T07:24:34.000Z" } ], "analyses": { "subjects": [ "58J50", "35P25", "81U05" ], "keywords": [ "microlocal properties", "scattering matrices", "pseudodifferential operator", "born approximation type function", "scattering matrix" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1407.8299N" } } }
